To all whom it may concern:

Be it known that L .ll'niiimii H. iVJxL- DRON, a citizen of the Uniiecl States. and a resident of New Brunswick, county of Mich dleseX, Shite of Yew Jersey. have invented certain Improvements in BloclePrinting Machines, of which the following is a specification. My invention relaies to a type of block priniing machine for printing material such as oil cioth, linoleum, and other fabrics which are fed intermittently through a inachine and in which there is a series of reciprocating hloch carriers which Gerry the printing blocks which make "he impressions on the material as is'fecl thlxLgh the man chine.

The object of my invention is to provide a mechanical 111851113 for automatically controlling the block carriers in order that any clesirecl block can make an impression at any time, so eh t the machine can print bordered rugs, or mars. anilsiniilar floor or table coverings.

Reierring to line drn'o ings; IS the main frame of my improved block m'iniing; ninchine 2, are the recinrocznhin block carriers adaptecl to travel in guides 3 secured to the upper member of the frame A, 4 are the blocks, which are s'curecl to the block carrier. The block carrier. in the present instance, consists of two rersiczil members 5 vi \,h are adapted to the guides 3 and a. transverse ineinher 6 which, extends across the machine and 4 are directly secured. T. .7 are the usual Wheels w l :n cravel on in s-eciificaiion of Letters Eaten t.

The framev is guided in ii heaiing secured to ihe main frame 1 of the nnichine, as clearly shown in Fig. 2, than she enzn 3G rotates-a longituclinul motion will he imparted to the will be moved toso that the control Mounted Word or from the clu zch of any particular carrier is governedby its cam. in the present insi ance, there .is a

r ch carri rods bein requires. 1 0 are driven LQVG; 26 thereon nal shaft 34 mounted in bearings 35 driven in any suitable manner from the main driving elements of the machine.

The fabric, in the present instance, travels over a table 36, and endless conveying belts 37 having prongs 38 engage the edges of the fabric. These belts pass around drums '39 on a shaft 40 at each end of the machine. One of these shafts is a driven shaft so that the driven mechanism is intermittent as in the ordinary machines of this type, so that the fabric moves a certain distance and then-remains stationary during the time the will actuate the mechanism. so that the corprinting blocks are making thelmpression.

The operation is as follows :If the machine is provided with a number of carriers, each carrier is controlled by a cam'and these cams are so arranged that, as they rotate,

certain of the shafts 10 will be driven by blocks, then the entire rug, if of one color,

can be printed withthreeblocks. If the rug is to be; printed in two colors, six blocks will be necessary, each set of'three supplying a given color. One block of each will have the right hand border thereon and part of, the body of fther'ug. Anotherblock; will have the left hand border and a portion of the body of the rug, and the third block will have, the balance of the body'of the rug and the two side strips which connect the end border; The camsgar'e arranged so that the blocks can print independently the right hand border, for-instance, andwhile that surface is passing through the machine the other blocks will-be held out of engagement until their special portion of the fabric is printed, at which time their particular cams I rect impressionf will" be me de:

In Figs. 3 andf8,,.l have shown three rods 24, 24 and 24;; The rod '24 terminates at, T the shaft 10, "whjile-"therod 24 extends to the second shaft-10. and the rod 24" extends to the third shaft 10*. If a three color rug is to be printed it will only take three cams and three rods, These rods, instead of terminating at the several shafts 10, 10,and 10 maybe continued to the other series, as illustrated in diagram,

' Fig. 9, so that the shafts 10, 10 and 10 will be'driven in unison and their several blocks will print at the same t1meone block print ing one color and another block printing a diflerent color, but the space printed by the block controlled by the shaft 10 will not be printed upon again until it is directly in line with the block controlled by the Shaft 10= and then not again until in line with the" .block controlled by the shaft 10.

This scheme can be carried out in any number of colors, according to'the length of the ma chine-to which the invention is applied.

clutch mechanism through which the trans- ,verse shafts are-driven from. the driving shaft; and automatic means for controlling the clutches so that certain of the shafts can be driven 'while others remain station-b arv.
